Granted: 2000-02-15
Abstract: A line circuit whose circuit components are selectively controllable by a microprocessor/DSP to provide normal BORSCHT functions or to be selectively tested without need for an electromechanical relay to isolate the line circuit from the loop conductors.  The conventional line transformer is advantageously replaced by a loop current feed resistor network and either a high voltage or a lower voltage battery may be connected to provide loop current to the resistor network through a current regulator circuit and battery switch circuit.  In normal operation, an ac feedback path, which includes the line receive amplifier, increases the terminating impedance above the dc value of the feed resistors so the loop termination resistor network may match the characteristic impedance of the loop at the audio frequencies employed.  In the testing mode, the microprocessor/DSP selectively applies or denies power to the line driving and receive amplifiers as well as to a level shifting circuit interposed between the codec analog output and the input to isolate or include these components or to provide a codec loop-back path.  The condition of the dc feed resistors and protective fuses, the condition of the loop closure detector and of the ringing generator are reported to the microprocessor/DSP over the same terminal normally used for reporting the on-hook and off-hook status of the loop.

Abstract: Cette invention décrit des techniques de recherche ou de sélection de nouvelles enzymes protéolytiques. Il est possible de sélectionner ces fonctions enzymatiques à partir de bibliothèques d'ADN chromosomique isolé ou de groupes d'ADN mutagénisé codant pour une fonction protéolytique. Dans la technique de sélection utilisée dans le cadre de cette invention, notamment, on sélectionne un gène de phage codant pour un produit génique nécessaire à la production d'un phage. On introduit ce dernier, porteur du gène modifié, dans un hôte ainsi que des bibliothèques d'ADN présentes dans un véhicule de clonage dans des cellules hôtes. La croissance de ces dernières s'effectue dans des situations où les bibliothèques introduites sont exprimées dans les cellules hôtes. C'est à partir de la production d'un phage infectant que l'on met en évidence la présence d'une fonction enzymatique capable de diviser la cible peptidique.

Abstract: Cette invention concerne un cylindre de tamis, un tamis, un procédé de fabrication du cylindre de tamis et un procédé d'utilisation de ce cylindre de tamis. Cette invention permet de maximiser la capacité dudit tamis sans diminuer la robustesse du cylindre de tamis et tout en permettant d'obtenir un flux sans mélange des matières acceptées. On fabrique un cylindre de tamis (10) de manière classique à la différence près que l'on fixe à demeure (généralement au moyen d'un soudage continu ou ponctuel par faisceau électronique ou au laser ou encore d'un soudage par résistance direct) au moins un anneau de renforcement (14) à au moins une majorité de zones planes (22) (et généralement à pratiquement toutes ces zones) qui séparent l'une de l'autre des rainures (18) en enfilade, au niveau de la surface de sortie du cylindre. Chaque soudure a une largeur de 1 à 3 mm environ, c'est-à-dire une largeur très faible, mais cette largeur représente généralement 75 % environ de la largeur de la zone plane où elle se trouve, et la longueur de chaque soudure représente au moins 50 % de la largeur de l'anneau de renforcement (14) au niveau de la soudure. De cette manière, la longueur efficace des fentes des cylindres de tamis peut représenter de 65 à 90 % de la longueur totale du tamis, alors qu'elle n'en représente que 45 à 55 % dans le cas des cylindres de tamis classiques. Ces cylindres de tamis sont particulièrement efficaces en ce qui concerne le tamisage des pâtes à papier dans l'industrie des pâtes à papier.

Abstract: A moulded plastics golf shoe cleat comprises a disc 14 from an upper surface of which a screw-threaded spigot (not shown) projects for attachment of the cleat to a shoe sole. A ring of barb-forming elements 16 stands on an undersurface 18 of the disc, each element comprising a convergent free-end portion forming a ground-engaging barb which terminates at an edge 24 extending tangentially of the ring. Each barb projects in a direction which makes an acute angle with the undersurface 18 of the disc 14, the barbs being resiliently deflectable to increase the angle whereby resistance to sliding of the cleat in use over penetrable ground may become increased by increased penetration of the barb into the ground. The barbs are aligned along chords to the ring, being uniformly turned out of radial alignment so as to discourage unscrewing of the cleat in use.

Title: Method of enhancing call processing in a number portability environment
Inventor: WILSON LANCE WAYNE
IPC: H04Q11/04
Filed: 1998-05-11
Granted: 2002-04-30
Abstract: A method is provided which reduces post-dial delay in a number portability environment.  In particular, a switching office which controls call routing to portable numbers (NPA-NXXs) contains a cache for which location routing number response information may be stored.  The processing office concurrently checks the cache for LRN response information corresponding to the dialed number and launches a query to a number portability database. Thus, if the LRN response information in the cache is valid then the call will be routed in the timeliest manner.  However, if either the cache does not have any LRN response information or the LRN response information in the cache proves not to be valid then, the switching office will have received the LRN response information from the database more quickly based on the concurrent launching of a query.  Therefore, a more timely attempt at establishing a proper connection to the dialed number will occur thereby reducing post-dial delay, regardless of whether or not the dialed number is ported.

Abstract: A method of suspending an electric submergible pumping system within a wellbore includes inserting an electric cable within a conduit, such as coiled tubing. One end of the conduit is sealed with one end of the electric cable extending out therefrom. The conduit is filled with a fluid of sufficient volume and sufficient density to float the electric cable within the conduit when the conduit is disposed within a wellbore. An electric submergible pumping system is connected to the conduit, and the electric cable is connected to an electric motor of the electric submergible pumping system. Thereafter, the electric submergible pumping system and the conduit are inserted into the wellbore. Since the cable is floating, i.e., self supporting, within the conduit there is no need for cable anchors or other devices to transfer the weight of the cable to the conduit.
